1/// Macro to create a `Matrix` from a nested array.
2///
3/// # Example
4///
5/// ```
6/// use numberlab::mat;
7/// use numberlab::structure::matrix::Matrix;
8///
9/// let matrix = mat![
10///     [1, 2, 3],
11///     [4, 5, 6],
12///     [7, 8, 9]
13/// ];
14///
15/// assert_eq!(matrix, mat![[1, 2, 3], [4, 5, 6], [7, 8, 9]]);
16/// assert_eq!(format!("{}", matrix), "\n 1 2 3\n 4 5 6\n 7 8 9\n");
17/// ```
